you might read up on hive removal. you'll find lots of stuff on here with pictures. put an add on craigslist.com, or list with your fire department, bee store, etc. that way, you may be able to do some simple removals and get some bees.
some people charge. i don't have the experience to feel comfortable doing that and i am only doing out buildings, and swarms. no houses, etc. you might be surprised how many people have bees in the barn wall and want them removed.
